Reaction Steps

Methylhydrazine (47 mg) (1.02 mmol) are added at 0° C. to a solution of 530 mg (1.02 mmol) of N-[(4,7-dichloro-2,2-diphenyl-1,3-benzodioxol-5-yl)methoxy]phthalimide in 10 ml of absolute dimethylformamide. The mixture is stirred at 0° C. for 1 hour and at room temperature for 4 hours. The solvent is removed in a high vacuum at room temperature and the residue is chromatographed on 30 g of silica gel (0.063-0.2 mm). The product is eluted with dichloromethane/ethanol (19:1 v/v). There are obtained 310 mg of 5-[(aminooxy)methyl]-4,7-dichloro-2,2-diphenyl-1,3-benzodioxol as a colourless oil.
